Add support for Python 3.13

[JasonGrace2282]

Python 3.13 has been out for a week or two now, it's highly probable that new users to Manim may start off with python 3.13. As such, we should start testing it.

All tests pass locally on my machine, and looking through the porting guide there isn't much to be concerned about (except a small change w.r.t. functools.partial which I don't think applies to us).

This COMPLETELY REMOVES the upper python version bound. See https://iscinumpy.dev/post/bound-version-constraints/ for why upper bounds on python versions is a terrible idea.

(marking as a draft until tests pass on all operating systems)

Changes

• Remove python upper bound
• Use scipy >=1.14.0 for python >=3.13
• Require moderngl-window >= 3.0.2
• Require numpy>=2.0
• Add dependency audioop-lts after removal of stdlib audioop library.

Tried to replicate the 3.13 issue on Windows locally, effectively killed my stream doing so. :-)

Alright, this was rather annoying -- but here we are; our tests are passing for all OS/Python version combinations.

There were a bunch of breaking changes mandated due to the need to upgrade numpy to >=2.0 (mainly in the doctests). Actually requiring numpy>=2.0 makes our dependencies unsatisfiable due to moderngl-window requiring numpy<2 (reported upstream, likely to be resolved with their next release).

I am not sure what to do with this PR in the meantime; probably we will just have to wait until moderngl-window has a new release.

[JasonGrace2282]

Should this be reverted?

This fixed a bunch of tests that were mistakenly run with the opengl renderer, we should keep it for now.

Curiously, the pipeline failed again in the pathological case, am looking into details.

Official Python 3.13 support, here we go! 🚀
